Amino acid carriers of Ricinus communis expressed during seedling development: molecular cloning and expression analysis of two putative amino acid transporters, RcAAP1 and RcAAP2.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study reports on the isolation of two putative amino acid carrier cDNAs, RcAAP1 and RcAAP2, from Ricinus communis. Northern analysis shows that RcAAP1 and RcAAP2 are expressed abundantly in the cotyledon and root tissues of developing seedlings and at lower levels in the endosperm and hypocotyl. In the mature plant low expression was observed in the source and sink leaves. We have further characterized the expression of RcAAP1 in Ricinus roots by in situ hybridization. The transcripts are localized in many cell types of the root tip region, including the epidermal and cortical cells, but the highest expression was observed in the cells of the stele situated adjacent to the xylem poles. This is the first report describing the cellular expression of an amino acid transporter in roots, and the results are discussed in relation to the physiological role of this transporter.
